This quick mug bread is designed to be very low in carbohydrates and is perfect when you want a small serving of bread without making a whole loaf. It has a soft, slightly chewy texture and works well for breakfast, sandwiches, or as a side with soup.
Note: Truly zero-carb bread is difficult to make because ingredients such as eggs and dairy contain small amounts of carbohydrates. This recipe is therefore best described as zero-carb-style or very low-carb, depending on the brands and ingredients used.
Ingredients
- 1 large egg
- 2 tablespoons almond flour
- 1 tablespoon melted butter
- 1/4 teaspoon baking powder
- A small pinch of salt
Instructions
1. Prepare the Mug
Choose a microwave-safe mug or small ramekin.
Lightly grease the inside with a little butter to make the bread easier to remove.
2. Mix the Egg
Crack the egg into the mug.
Beat it thoroughly with a fork until the yolk and white are completely combined.
3. Add the Ingredients
Add the almond flour, melted butter, baking powder, and salt.
Stir everything together until you have a smooth batter.
Make sure there are no large pockets of flour remaining.
4. Microwave
Place the mug in the microwave.
Cook on high for approximately 60–90 seconds.
The exact time depends on your microwave. The bread should look set and feel firm in the center.
Avoid overcooking because it can make the bread rubbery or dry.
5. Rest
Carefully remove the mug because it may be hot.
Let the bread rest for 1–2 minutes.
Run a knife around the edge and gently remove the bread from the mug if desired.
6. Slice and Serve
Slice the mug bread in half and serve warm.
It can be toasted lightly in a dry skillet for a crispier outside.
Serving Ideas
Try your mug bread with:
- Butter
- Cream cheese
- Avocado
- Eggs
- Sliced chicken
- Tuna salad
- Low-carb vegetables
- Sugar-free spreads
Tips for Better Mug Bread
Beat the egg well: This helps create a more even texture.
Don’t overcook: Start with 60 seconds and add extra time in short increments if necessary.
Use a wide mug: A wider container produces a bread shape that is easier to slice.
Toast it: After microwaving, lightly toast the bread in a skillet for a firmer crust.
Storage
Because this is a small, quick bread, it tastes best immediately after cooking. If you need to store it, allow it to cool completely and keep it covered in the refrigerator for up to 1 day. Reheat gently before serving.
Final Result
In just a few minutes, you can make a warm, soft low-carb mug bread with simple ingredients. It is especially convenient when you want a single serving rather than an entire loaf.
